Answer:
C: Plates float on the liquid mantle located below the crust.
Explanation:
Plates at our planet’s surface move because of the intense heat in the Earth’s core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.
Scientists once thought that Earth’s plates just surfed on top of the mantle’s giant convection cells, but now scientists believe that plates help themselves move instead of just surfing along. Just like convection cells, plates have warmer, thinner parts that are more likely to rise, and colder, denser parts that are more likely to sink.
Answer:
They live in areas that they can get resources from.

For example food, shelter, etc.
Answer:
A diatomaceous earth is ia an example of light-colored sedimentary rock
Explanation:
- Composed chiefly of siliceous shells of diatoms are soft and are friable rock this rock often floats on the water just like pumice before the pores are initially filled with water and are usually white.
- The silica is formed from the weathered silicate rocks and besides these deposits are geologically young, they have become abundant since the past 50 million years ago.
- The wine and beer industry make use of diatomaceous earth also added in toothpaste as it has milder abrasive properties.
